The invention relates to the technical field of forklift portal frames, and particularly discloses a forklift portal frame balance adjusting device which comprises an outer portal frame. An inner door frame is arranged on the inner side wall of the outer door frame; a connecting plate is fixedly connected to the side wall of the top end of the inner portal. The bottom surface of the connecting plate is fixedly connected with a pair of supports; first threaded holes are formed in the two supports; a pair of lifting oil cylinders located at the bottoms of the two supports are arranged on the bottom wall of the outer portal frame, and the output ends of the two lifting oil cylinders are coaxially and rotationally connected with adjusting bolts. The pair of adjusting bolts can be in threaded connection with the inner side walls of the two first threaded holes respectively; locking mechanisms capable of locking the adjusting bolts are arranged on the two supports; the lifting oil cylinders are driven to move in the vertical direction by rotating the adjusting bolts, the output ends of the two lifting oil cylinders are located on the same horizontal line, the leveled adjusting bolts are locked through the locking mechanism, and then the balance adjustment work of the portal is conveniently achieved.

    本发明涉及叉车门架技术领域,具体公开了叉车门架平衡调节装置,包括外门架;外门架内侧壁上设置有内门架;内门架顶端侧壁上固接有连接板;连接板底面固接有一对支座;两支座上均开设有第一螺纹孔;外门架底壁上设置有一对分别位于两支座底部的起升油缸,两起升油缸的输出端均同轴转动连接有调节螺栓;一对调节螺栓可分别螺纹连接在两第一螺纹孔内侧壁上;两支座上均设置有可锁定调节螺栓的锁定机构;通过旋转调节螺栓带动起升油缸进行竖直方向上的移动,使两起升油缸输出端位于同一条水平线上,并通过锁定机构对调平后的调节螺栓进行锁定,进而便捷实现门架平衡调节工作。
